Water Garden Ltd are accredited OASE 5 Star Retailers and we hold large stocks of spare parts and filter foams in stock at all times for the most popular replacement parts for your OASE pond filter. We do not offer replica parts as these will compromise your filtration system and may lead to product warranty issues and upholding of the Clear Water Guarantee. All OASE filters use high grade, specially developed filer sponges which will provide optimal performance. We also carry a range of spare parts for the ProfiClear Drum Filtration systems such as filter sieves, spare drum gaskets and lubricants to ensure the Drum Filter is operating at its most efficient, all year round. Many of the OASE ProfiClear drum filters can be retrofitted with coarser or finer pore sieves to reduce cleaning cycles or further increase debris extraction down as low as 30 microns.
